A31 01' APPLY!!! FILLING MATERIALS 1'0 PASTRY Application filed April 80, 1928, Serial Io.

My invention relates to the art of applying g materials to pastry having cavities for t e reception of such materials.

It is an o ject of my invention to provide 6 amethod of performmg this operation-or sequence of operations-so as to prevent damage to the past and deterioration to the filling materia an to this end Icharge' the cavit1es, smooth and press down the Hing material, and return the excess material to the supply, by'resilient means.

It is another object of my invention to provide a machine for rforming ,my method, and to this end in rant by which the material is distributed, erall a roller, I provide a resilient wiper whic performs the functions aforesaid, with or without the assistance of other appliances, as will be described.

Various means have been' proposed for filling thecavities of pastry, as wafiies, with a filling material which W111 be referred to as cream but obviously may be any other substance. However, the problem was never solved satisfactorily because due consideration was notgiven to the fragile and delicate character of the past and the cream. Particularly in the case of othy substances it is necessar that any treatment involving friction shou d be avoided as it im arts a dense and streaky constitution to e substance.

In the accompanyin drawings a machine by which my method is performed, is illustrated by way of example.

In the drawings .Fig. 1 is a transverse section, and

Fig. '2 is an elevation of the machine, viewed from the right in Fig. 1. v

The articles genof the part the hopper which 274,015, and in Germany April 80, 1981.,

which are to be filled are indicated at 4 and are illustrated as wafiies by way of example. 16, 16' are side shields between which the wafiies 4 are moved by the con'veyer 3 and preferably means are lprovided for va ing the clearance of the s 'elds as re uire by the varyin width of the articles. s shown in Fi 2, t e shield 16' is fixed to the frame and t e shield 16 is ada ted to be displaced with respect to the shiel 16' by a handle 15 which is carried to slide in the frame part 5 at the right of the machine.

6 is a scraper or w1per arranged in front of the roller 2 and above the articles 4 which scrapes the cream from the roller 2 and iles it. up in a body or crest 7 from whic it flows into the cavities of the articles 4.

Several layers of cream may be applied if desired.

Ifit is desired that the cream should form a layer above the articles 4 shoes 12 are provided on the lower faces of the wiper 8 which resemble skids and are supported on the articles 4 as they move along. Screws 13 are provided for adjusting the shoes 12 so as to vary the clearance between the articles and the lower edge of the wiper.

14 are holding-down brackets arranged in front of the wiper 8 which are adapted to be adjusted by screws 14' and serve for preventing rising and breakage of the articles due to one of them creeping'to the top of the other.

Instead of the roller 2, a conveyer might be rovided which, in order to reduce the liab1lityto fracture, should engage the articles onl for a short distance.

Thecreamisalsotreate very so delicately and without being subjected'to any amount of friction throughout its way from the hopper 1 to the articles 4 and back to the hopper, if there is any excess. There is, consequently, no liability for the cream to become dense and streaky.

The'ho ding-down brackets 14 prevent any irregularity in the movement of the articles past the roller.2 in vertical direction, and laterally the articles are restrained by the shields 16, 16'. Small particles which. may become detached from the pastry notwithstanding the delicate treatment are intercepted by the rake 17 and prevented from being carried into the ho per with the returning excess cream. If t ere are any foreign bodies in the hopper the slide 18 is retracted by the handle 21 and such bodies are allowed to leave the hopper without interruption of the operation.
